A Direct Method for the Fabrication of Macro‐Porous SiOC Ceramics from Preceramic Polymers
Source abstract
Abstract
Cellular SiOC ceramics having a complex morphology were produced using two silicone precursors. Linear PDMS and two different silsesquioxanes (containing either methyl or methyl-phenyl side groups) were mixed, crosslinked and pyrolyzed at 1200 °C, resulting in the formation of macroporous ceramic components. Pore formation was attributed to the different behavior of the precursors upon pyrolysis. The amount of porosity depended on the amount of PDMS, which acted as a “sacrificial filler”, leading to the formation of pores ranging from a few microns to a few hundred microns.
